Full solution
Q. what could be possible 'one's' digits of the square roots of following number
- Understand the problem: Understand the problem.We need to find the possible 'one's' digits of the square roots of the number . This means we are looking for the last digit of the square root of .
- Consider possible digits: Consider the possible 'one's' digits of perfect squares.The 'one's' digit of a square root is determined by the 'one's' digit of the square itself. The possible 'one's' digits for any perfect square are , or because when you square the digits , these are the only digits that appear in the 'one's' place.
- Look at given number: Look at the 'one's' digit of the given number.The 'one's' digit of is . We need to determine which squares end in .
- Find squares with digit: Find the squares that end with the digit . No perfect square ends with the digit . Therefore, there is a math error in the question itself, as it assumes that a square root of a number ending in would have a 'one's' digit that we could determine. Since no perfect square ends in , the question is flawed.
